Here's a little background on what type of people I'm dealing with:
- They're all in the same university that I go to. It's a faculty of engineering that has the most strict entrance exam in my country, so we generally all have high intellectual levels (But incidentally outside of class they talk like any average person).
- Their subjects include but are not limited to fashion, sports, cars, money/work, or sometimes they just tell random funny stories, which are all topics that I can neither find interesting, nor able to talk about because I'm unaffiliated with anything related to those topics.
- Most of them are pretty good at social interaction, so I have high standards to meet.
- It's a grand total of 200 people(that are in the same classes as me). Most of the time, they're different groups of 5 that get together between classes or during long breaks. They're not strangers to me, in fact I've spoken to all of them at some point so I wouldn't be intruding by participating in a group conversation. But I wouldn't explicitly consider any one of them a "friend".
- I wouldn't call them judgmental at all, in fact I think they're a pretty nice and understanding set of people.
Leaving is preferably not an option. I'm not particularly good at socializing so I want to practice by participating in as many group conversations as I can. There isn't any group that I prefer more than others; they're all the same to me.
Note: I've already tried sparking up few topics that interest me (Mathematics, history, music, space exploration, controversial topics and sometimes started debates) but each time the conversation dies out very quickly, as opposed to a heated 1-hour debate they'd had on fuel-efficiency versus speed of modern production cars.
Also, I'm aware of other questions asked on the forum that are similar to mine in topic, but they ask very different things.
EDIT: Found some interesting ideas that gave me some perspective and could be helpful for anyone who's inquiring on this topic:
